To (ZZZ whom it may concern Be it known that we, J OHN T. LAMM and Fnnu K. lIUFFMAN, citizens of the United States, residing at Julesburg, in the county of Scdgwick and State oil. Colorado, have in vented certain new and useful Improvements in Radiators, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in radiators and has relation more particularly to a device of this general char acter especially designed and adapted for use in connection with the cooling system 0t an internal combustion engine, and it is an object of the invention to provide a novel and improved radiator whereby the water is caused to travel therethrough in a tortuous or more particularly a Zigzag course or path of travel.

Another object of the invention is to provide a novel and improved radiator having disposed therethrough horizontally directed air tubes and wherein the interior of the radiator is divided vertically into a plurality of compartments or chambers with adjacent chambers in communication one with the other, whereby the water within the radiator is caused to travel therethrough in a tortuous or zigzag course.

An additional object of the invention is to provide a novel and improved radiator wherein the walls or faces thereof are corrugated in order to increase the radiating area and whereby the cooling of the water within the radiator is materially facilitated.

Furthermore, it is an object of the invention to provide a novel and improved device of this general character wherein the air tubes are maintained in applied position in a manner whereby one of the tubes may be replaced independently of the remainder of the tubes and without the necessity of dis placing the radiator from applied or working position.

The invention consists in the details of construction and in the combination and arrangement of the several parts of our improved radiator whereby certain important advantages are attained and thedevice rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of our invention will hereinafter be definitely claimed.

In order that our invention may be the invention Fig. 2 is an enlarged fragmentary sectional view taken substantially on the line 22 of Fig. 1; and

Fig. 8 is a view in top plan of one of the plates as herein embodied.

As disclosed in the accompanying draw ings, R denotes our improved radiator in its entirety and which may be, if desired, suitably mounted within a radiator shell (not shown) although the structure of our improved radiator is such that the shell, under certain conditions, may be dispensed with.

Our improved radiator, as herein disclosed, comprises two sections. A and B, the upper section A. constituting the upper tank of the radiator and the lower section B constituting the core. The walls of the sections A and B are preferably made of sheet cop per. lVhen the sections are assembled, the adjacent marginal portions thereof are suit ably connected or'united as indicated by the scam I. The upper or tank section A is also provided with conventional type of a filler neck 2 whereby the radiator and the coactinn; cooling system may be properly filled with water or other fluid.

The vertical walls of the section of the radiator ll have produced therein the horizontally disposed and vertically spaced corrugations 3, said corrugations being preferably V-shape in cross section with their apices disposed inwardly of the section B. it is also preferred that said corrugations 3 be equidistantly spaced. Between each pair of adjacent corrugations 3 isa flat surface 4 and disposed through said flat portions l of the front and rear walls of the section A are the air tubes 5. Adjacent air tubes are in relatively close proximity and have their opposite end portions headed to overlie the outer faces of: the front and rear walls of the section B and said beads 6 are soldered thereto. By this means, a single tube 5 can be readily removed and replaced independently of the remainder of the tubes and without the necessity of disassembling the radiator or removing the radiator from applied or working position.

Arranged within. the radiator R is a plurality of horizontally disposed plates 7, preferably of galvanized iron. 'Each of these plates rests upon diametrically opposed corrugations 3 in all of the walls of the section B and one end portion of the plate 7 is provided with a relatively large recess or opening 8.

In the assembled structure, the plates 7 are preferably equidistantly spaced with the recesses or openings 8 of adjacent plates at opposiue sides-of the radiator B so that the water or other fluid within the radiator will travel in a tortuous or zigzag path or course whereby the cooling thereof is materially facilitated and especially by the air passing through the tubes 5. It is also to be understood that the corrugations 3 afford an increased area for the radiation of the heat whereby the cooling of the water or other fluid within the radiator is materially facilitated.

We also find it of advantage to provide each of the plates '7 in the end portion thereof remote from the recess or opening 8 with a restricted drain opening, 9 whereby the requisite circulation of the water or other fluid is materially facilitated. The drain opening 9 is particularly advantageous when the radiator stands in an inclined position.

Ihe pans 7 divide the interior of the radiator R or more particularly the section 13 thereof into a plurality of superimposed chambers or compartments and the lowermost of such compartments serves as the bottom tank and has in communication therewith an outlet connection 10 of any ordinaryror preferred type. The upper section A has in communication therewith an inlet connection 11. It is also to be understood that our improved radiator may be employed with a thermo-siphon cooling system or any other system wherein water or other liquid is employed.

in practice, it is also to be understood that our improved radiator is adapted for use in connection with passenger automobiles, trucks, tractors gasolene engines, or any machine which embodies a l1qu1d cooling system.

From the foregoing description, it is thought to be obvious that a radiator constructed in accordance with our invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that our invention is susceptible of some change and modification without departing from the principles and spirit thereof, and for this reason, we do not wish to be understood as limiting ourselves to the precise arrangement and formation of the several parts herein shown in carrying out our invention in practice except as hereinafter claimed.

We claim 5 1. A radiator of the class described comprising a hollow casing having induction and eduction openings at the top and bottom thereof, and a plurality of vertically spaced plates arranged within the casing and dividing the same into superimposed compartments, an end portion of each of the plates eing provided with an opening affording communication with the compartment immediately therebelow, the walls of the easing being provided with inwardly extending corrugations, certain of said corrugations serving as supports for the plates.

2. A radiator of the class described con1- prising a hollow casing having induction and eduction openings at the top and bottom thereof, a plurality of vertically spaced plates arranged within the casing and dividing the same into superimposed compartments, an end portion of each of the plates being provided with an opening affording communication with the compartment immediately therebelow, the walls of the casing being provided with inwardly extending corrugations, certain of said. corrugations serving as supports for the plates, and air tubes extending through the casing at points between adjacent corrugations.

In testimony whereof we hereunto affix our signatures.
